Samuel Horwitz is better known as whom?

Samuel Horwitz (March 11, 1895 – November 22, 1955), was known professionally as Shemp Howard, an American actor and comedian. He was called "Shemp" because "Sam" came out that way in his mother's thick Litvak accent. He is best known as the third Stooge in the Three Stooges, a role he played when the act began in the early 1920s (1923–1932), while it was still associated with Ted Healy and known as "Ted Healy and his Stooges"; and again from 1946 until his death in 1955.

Curly was felled by a debilitating stroke on May 6, 1946. Curly had already suffered a series of strokes prior to the filming of "If a Body Meets a Body" (1945). Shemp agreed to fill in for Curly in Columbia's popular Stooge shorts, knowing that if he refused, Moe and Larry would be out of work. He intended to stay only until Curly recovered, which never happened as Curly's health continued to worsen. Curly died on January 18, 1952, at the age of 48. Shemp agreed to remain with the group permanently.

In November 22, 1955, Howard went out with associates Al Winston and Bobby Silverman to a boxing match (one of Howard's favorite pastimes) at the "Hollywood Legion Stadium" at North El Centro and Selma Avenues, one block above the Hollywood Palladium. While returning home in a taxi that evening, Howard died of a massive heart attack, at the age of 60. He had just told a joke and was leaning back, lighting a cigar, when he suddenly slumped over on Winston's lap, burning him with the cigar.
